In addition to the known alkaloid peganine (1) from young plants of the Acanthacea Adhatoda vasica, the base anisotine (7) and the three new alkaloids vasicoline (4), adhatodine (5), and vasicolinone (6) were isolated and analysed. Mainly on the basis of spectral properties (UV., IR., NMR. and mass spectrometry) the structures were assigned. By atmospheric oxygen the bases vasicoline and adhatodine are oxidized in position 7; it is therefore remarkable that these bases are present as such in the plant.
